How many books to stop a bullet
WebThe kinetic energy of the bullet is $\frac12 mv^2 \approx 1$ kilojoule. Spreading the bullet's energy over the stopping time gives an average power of 175 kilowatts. If you make some hand-waving assumptions that the mechanism for stopping the bullet is inefficient you might multiply this power by a factor of 10–100. This is a lot of power! WebThose wanting an auto-pistol with .357 Magnum-like performance, which from duty guns had stopping power up to 96 percent, should consider the 357 SIG caliber. The .40 S&W is considered as a “bridge caliber.”. The 45 ACP is an effective caliber. The large diameter and heavy weight of the bullet are the foundation for the “momentum ...

WebThe smaller the object is, the higher the terminal velocity. For a bullet, one estimate that I have read for terminal velocity is around 300 ft/sec (about 200 mph). Since that’s a lot slower than a bullet leaves a gun nozzle, it seems that the air resistance really will have a big effect on the speed of the falling bullet.
WebFeb 19, 2016 · A stopping distance is then x 0 = v 0 τ. you need a magnetic field: B = ζ ρ v 0 / x 0. For a lead bullet, ζ = 22 ⋅ 10 − 8 Ω m, ρ = 11.3 ⋅ 10 3 k g / m 3. To stop a bullet in x 0 = 1 m long distance, starting at typical velocity v 0 = 300 m / s, you need B = 0.9 T. A large, but still reasonable field, but not entirely crazy - it can ...
